During a U.S. speaking tour, renowned primatologist and environmental advocate Jane Goodall passed away of natural causes in California on October 1, 2025, at the age of 91.
Goodall is globally recognized as a leading authority on chimpanzees. Beginning in the 1960s at Gombe National Park, Tanzania, she was the first to document chimpanzees using tools, displaying complex social behavior and emotional interactions, challenging traditional boundaries between humans and animals.
She founded the Jane Goodall Institute in 1977 and launched the Roots & Shoots youth environmental program, now operating in multiple countries worldwide to encourage young people to participate in conservation and environmental issues.
Her legacy spans scientific contributions, advocacy for biodiversity, animal rights, and the future of the planet. Tributes have poured in internationally, with many noting her passing as a major loss for the environmental and scientific communities.
